Purpose and goal

The project partners will conduct a pilot project to study high temperature brazing of stainless steel with synchrotron based techniques The overall aim is to gain insight into the brazing process used by Alfa Laval in the manufacturing of heat exchangers, thus accelerating the commercialization of a new product. The goal is to generate a detailed understanding of the complex evolution of the microstructural phases during brazing that affect the final performance of the heat exchanger.

Expected results and effects

Strong collaboration between Alfa Laval and the Faculty of Engineering (LTH), Lund University will generate state of the art research on metal joining and ultimately result in an optimization of the manufacturing process and accelerated commercialization of next generation heat exchangers. Furthermore, the project is expected to generate valuable knowledge of how Alfa Laval can solve complex materials and production related challenges using synchrotron light, thus increasing the rate of innovations and launch of new products.

Planned approach and implementation

The defined goal will be achieved by an in-situ high temperature X-ray diffraction experiment at a synchrotron light source. The experiment will be executed at DESY/Petra III, SOLEIL or MAX IV. The choice of synchrotron light source will be based on an ex-situ pre-study that will be conducted at LTH. The in-situ study will be performed at a brazing temperature of over 1200 ° C in an inert atmosphere. The evolution of the microstructural phases of the stainless steel in the heat exchanger plate and the braze filler will be monitored continuously using diffraction.
